Broken pins are from a Middle East land (7)
I believe the answer is:
persian
'a middle east land' is the definition.
Although both the answer and definition are adjectives, I don't see how they can define each other.
'broken pins are' is the wordplay.
'broken' indicates anagramming the letters.
'pins'+'are'='pinsare'
'pinsare' with letters rearranged gives 'PERSIAN'.
'from' is the link.
Can you help me to learn more?
(Other definitions for persian that I've seen before include "Breed of cat" , "From Iran?" , "Iranian language" , "Type of cat or carpet" , "Long-haired cat" .)
